1500 - Rear Brake Pad Replacement 🛠️

Got it—you want to replace the rear brake pads on your 2015 1500 (4WD, rear disc brakes). I’ll walk you through it step by step.

Quick questions before you start:

• 🧰 Do you have a floor jack and jack stands (stands that safely hold the truck up)?
• 🧱 Do you already have new rear pads and optional hardware kit (the small metal clips the pads slide in)?

If not, you can still read through this to see what you’ll need.

1500 - Parts, Specs & Tools 📦

Parts you’ll need:

• 🧩 Rear brake pads (set for both sides)
  • Always replace pads on both rear wheels together.
• 🧩 Rear pad hardware kit (pad abutment clips) – strongly recommended
• 🧩 Brake cleaner spray
• 🧩 High-temp brake grease (for pad contact points, not friction surfaces)

Key torque specs (rear):

• 🔧 Caliper guide pin bolts: ~26 ft-lb (35 N·m)
• 🔧 Caliper bracket bolts: ~120 ft-lb (163 N·m)
• 🔧 Wheel lug nuts: 130 ft-lb (176 N·m)

Use a torque wrench if you can; it’s a tool that lets you tighten bolts to a specific force.

Tools you’ll need:

• 🛠️ Floor jack and jack stands
• 🛠️ Wheel chocks (blocks to stop the truck from rolling)
• 🛠️ Lug wrench or 21 mm socket for lug nuts
• 🛠️ Socket set (metric):
  • Caliper guide pins: usually 13 mm or 14 mm
  • Caliper bracket bolts: usually 18 mm
• 🛠️ Breaker bar (long handle for tight bolts)
• 🛠️ Torque wrench (for final tightening)
• 🛠️ C-clamp or disc brake piston tool (to push the caliper piston back)
• 🛠️ Flat screwdriver or small pry bar
• 🛠️ Wire brush (to clean rust from bracket)
• 🛠️ Wire or bungee cord (to hang the caliper)
• 🛠️ Safety gear: gloves, safety glasses

1500 - Safety & Prep ⚠️

• ⚠️ Work on a flat, solid surface – never rely on the jack alone; always use jack stands.
• ⚠️ Parking brake OFF – you have rear disc brakes; the parking brake is a drum inside the rotor. Leave it off so the rotor and pads can move freely.
• ⚠️ Engine off, key out.
• ⚠️ Do one side at a time so you can look at the other side as a reference.

1500 - Lifting and Wheel Removal 🧱

1. Chock the front wheels 🧱
   • Place wheel chocks in front of and behind at least one front tire.
2. Break loose rear lug nuts 🔧
   • Use the lug wrench to loosen (but not remove) the rear wheel lug nuts about one turn.
3. Jack up the rear corner 🛠️
   • Place the jack under the rear axle tube near the wheel you’re working on.
   • Lift until the tire is off the ground.
4. Set jack stands 🏗️
   • Place a jack stand under the axle tube and lower the truck onto it.
   • Give the truck a gentle shake to confirm it’s stable.
5. Remove the wheel 🛞
   • Remove the lug nuts and take off the wheel.

1500 - Caliper & Old Pad Removal 🔩

1. Locate the caliper and guide pin bolts 👀
   • The caliper is the part that squeezes the pads onto the rotor.
   • On the back side you’ll see two small bolts (guide pin bolts) – one top, one bottom.
2. Remove caliper guide pin bolts 🔧
   • Use the correct socket (usually 13–14 mm) to remove both bolts.
   • If the pin spins, you may need a wrench on the flat of the pin to hold it.
3. Lift off the caliper 🪢
   • Gently pry the caliper away from the pads with a flat screwdriver if it’s stuck.
   • Do not let it hang by the hose – hang it from the suspension with wire or a bungee.
4. Remove the old pads 🧱
   • Slide the pads out of the bracket.
   • Note how they were installed (inner vs outer, any wear indicator tab).
5. Remove caliper bracket (if needed) 🔩
   • For a proper clean, remove the caliper bracket by taking out the two large bolts on the back (usually 18 mm).
   • These are tight; use a breaker bar.
6. Remove old hardware clips 🧩
   • Pop the metal clips out of the bracket where the pads sit.

1500 - Cleaning & Piston Reset 🧼

1. Clean the caliper bracket 🧽
   • Use a wire brush to clean rust and dirt from the pad contact areas.
   • Spray with brake cleaner and let it dry.
2. Install new hardware clips 🧩
   • Snap the new clips into the bracket in the same spots as the old ones.
3. Lightly grease contact points 🛢️
   • Apply a thin layer of high-temp brake grease on the areas where the pad backing touches the clips.
   • Do NOT get grease on the pad friction surface or rotor.
4. Push the caliper piston back in 🔧
   • Check the brake fluid reservoir under the hood; if it’s very full, you may want to remove a little with a clean syringe or turkey baster so it doesn’t overflow.
   • Place an old pad against the piston, then use a C-clamp or piston tool to slowly push the piston fully back into the caliper.
   • Go slowly to avoid damaging seals.

1500 - Installing New Pads & Reassembly 🧩

1. Reinstall the caliper bracket 🔩
   • Position the bracket back over the rotor.
   • Install the two large bolts and tighten to about 120 ft-lb.
2. Install new pads 🧱
   • Slide the new pads into the hardware clips.
   • Make sure the pad with any wear indicator tab goes in the same position as the old one (usually inner pad).
3. Check and lube guide pins 🛢️
   • Pull the caliper guide pins out of the bracket one at a time.
   • Wipe them clean and apply a thin coat of brake grease.
   • Reinsert them fully and make sure they slide smoothly.
4. Reinstall the caliper over new pads 🧷
   • Lower the caliper over the pads and onto the bracket.
   • Align the guide pin holes.
5. Install guide pin bolts 🔧
   • Thread them in by hand first to avoid cross-threading.
   • Tighten to about 26 ft-lb.

1500 - Wheel Install & Final Checks ✅

1. Reinstall the wheel 🛞
   • Put the wheel back on and hand-tighten the lug nuts.
2. Lower the truck 🏗️
   • Jack the truck slightly, remove the jack stand, then lower the truck to the ground.
3. Torque the lug nuts 🔧
   • Tighten lug nuts in a star pattern to 130 ft-lb.
4. Repeat on the other rear side 🔁
   • Do the same steps for the other rear wheel.
5. Pump the brake pedal 🦶
   • Before driving, pump the brake pedal several times until it feels firm.
   • This seats the pads against the rotors.
6. Check brake fluid level 🧴
   • Top up to the “MAX” line if needed with the correct brake fluid (usually DOT 3 or DOT 4 as marked on the cap).

1500 - Bedding In New Pads 🚗

• 🚦 Make 5–10 gentle stops from about 30–35 mph down to 5–10 mph, letting the brakes cool a bit between stops.
• 🚦 Avoid hard panic stops for the first 200–300 miles if possible.
